MODES FOR CARRYING OUT THE INVENTION
[0009] An electric-powered vehicle10 according to one embodiment will now be described.
[0010] As shown in Fig. 1, the electric-powered vehicle 10 includes two drive wheels 11
and one coasting wheel 12, which are arranged to be spaced apart from each other in
the traveling direction (the front-rear direction) of the electric-powered vehicle
10. The drive wheels 11 are spaced apart from each other in the vehicle width direction.
The axis of the drive wheels 11 extends in the vehicle width direction. The electric-powered
vehicle 10 also includes a frame 13, which is arranged between the two drive wheels
11 and the coasting wheel 12. The frame 13 rotationally supports the drive wheels
11 and the coasting wheel 12. By rotating the drive wheels 11 at different rotation
speeds, the electric-powered vehicle 10 is turned. The frame 13 has a substantially
tubular holder portion 13a, which extends in the vehicle width direction. The holder
portion 13a accommodates one or more electric motors (not shown), which drive and
rotate the drive wheels 11.
[0011] The frame 13 also has a substantially cross-shaped plate-like object mounting portion
13b, which extends in the traveling direction between the holder portion 13a and the
coasting wheel 12. The object mounting portion 13b is substantially parallel to the
ground. The object mounting portion 13b has two foot rest portions 13d, which extend
toward the opposite sides in the vehicle width direction.
[0012] The frame 13 further has a support portion 13c, which is connected to the distal
end (the rear end) of the object mounting portion 13b. The support portion 13c is
curved to rise as the distance from the object mounting portion 13b increases. A bearing
member 14 is arranged at the distal end of the support portion 13c. The bearing member
14 is pivotal about a turning axis, which extends in the vertical direction, relative
to the frame 13. The frame 13 rotationally supports the coasting wheel 12 through
the bearing member 14. By rotating the bearing member 14 about the turning axis, the
electric-powered vehicle 10 is turned.
[0013] The electric-powered vehicle 10 includes a stay 15, which is coupled to the frame
13 and extends upward from the frame 13. Specifically, the stay 15 includes two arm
portions 16, which are pivotally coupled to the opposite ends of the holder portion
13a. Each of the arm portions 16 extends upward from a position between the corresponding
one of the drive wheels 11 and the holder portion 13a. Each arm portion 16 is pivotal
about the axis of the corresponding drive wheel 11. The arm portions 16 are inclined
toward each other in the vehicle width direction in an upward direction. A handlebar
17 is supported by the upper ends of the arm portions 16 while being arranged between
the two arm portions 16. The handlebar 17 is pivotal about an axis extending in the
vehicle width direction. The handlebar 17 has two extended portions 17a and two holding
portions 17b. The extended portions 17a are extended from the upper ends of the arm
portions 16. The holding portions 17b project away from each other from the distal
ends of the extended portions 17a in the vehicle width directions. The distal ends
of the extended portions 17a are connected to each other in the vehicle width direction.
[0014] A substantially saddle-like seat 18 is supported by the upper ends of the two arm
portions 16 while being arranged between the two extended portions 17a of the handlebar
17. The seat 18 is pivotal about an axis extending in the vehicle width direction.
The distal end of the seat 18 has an opening that opens in the thickness direction
of the seat 18. The section around the opening forms a grip portion 18a. The opening
may be formed by either a dent or a through-hole.
[0015] A direction input device or manipulation device (not shown) such as a joystick is
arranged in one of the holding portions 17b of the handlebar 17. The direction input
device is electrically connected to an electronic control unit (not shown), which
is arranged at a suitable position in the electric-powered vehicle 10. The direction
input device outputs a manipulation signal corresponding to manipulation of the direction
input device by the user U to the electronic control unit. The electronic control
unit is electrically connected to the above-described electric motors and drives and
controls the electric motors in correspondence with the manipulation signal from the
direction input device. That is, the electronic control unit controls traveling of
the electric-powered vehicle 10 by controlling rotation of the two drive wheels 11
through driving and controlling of the electric motors. For example, by rotating the
electric motors normally, the electronic control unit causes the electric-powered
vehicle 10 to advance such that the drive wheels 11 precede the coasting wheel 12.
The direction in which the electric-powered vehicle 10 travels at this time will hereafter
be referred to as "the normal traveling direction". In contrast, by rotating the electric
motors reversely, the electronic control unit causes the electric-powered vehicle
10 to advance such that the drive wheels 11 follow the coasting wheel 12. The direction
in which the electric-powered vehicle 10 travels at this time will hereafter be referred
to as "the reverse traveling direction".
[0016] By changing the angle of at least one of the frame 13, the seat 18, and the handlebar
17 with respect to the stay 15, the electric-powered vehicle 10 is switchable selectively
among multiple modes in correspondence with the purpose of use by the user U. In other
words, the shape of the electric-powered vehicle 10 is changeable selectively to a
shape corresponding to each of the multiple modes. The multiple modes (the multiple
shapes) will hereafter be described.
[0017] A first mode of the modes is a ride mode used by the user U in a sit-down state.
As shown in Fig. 2, in the ride mode, the stay 15 extends upward while being inclined
in the reverse traveling direction with the handlebar 17 extending upward while being
inclined in the normal traveling direction. The seat 18 extends in the reverse traveling
direction from the upper end of the stay 15. In the ride mode, the user U is in a
posture in which the user U faces in the normal traveling direction, is seated on
the seat 18, and holds the handlebar 17 with the stay 15 located between the legs
in the vehicle width direction and the soles of the feet resting on the two foot rest
portions 13d. This allows the user U to electrically move the electric-powered vehicle
10 in a sit-down state on the electric-powered vehicle 10. The stay 15 is located
on the leading side of the object mounting portion 13b in the traveling direction
in the ride mode (the normal traveling direction).
[0018] A second mode of the modes is a cart mode, in which the electric-powered vehicle
10 is used as a cart. With reference to Figs. 3, in the cart mode, the stay 15 extends
upward while being inclined in the reverse traveling direction by a smaller angle
with respect to the vertical direction than in the ride mode. The seat 18 extends
downward along the stay 15. In the cart mode, the user U is in a posture in which
the user U faces in the reverse traveling direction, stands upright, and holds the
handlebar 17 at a position on the trailing side of the electric-powered vehicle 10
in the reverse traveling direction. This allows the user U to move the electric-powered
vehicle 10 by human power with an object B mounted on the object mounting portion
13b. The traveling direction in the cart mode (the reverse traveling direction) is
reverse to the traveling direction in the ride mode (the normal traveling direction).
Also, in the cart mode, the two drive wheels 11 may be driven by manipulating the
direction input device to energize the electric motors. This reduces the load on the
user U caused by carrying a heavy object.
[0019] A third mode of the modes is a Kickboard (trademark) mode. As illustrated in Fig.
4, in the Kickboard mode, the stay 15 extends upward while being inclined in the reverse
traveling direction by a smaller angle with respect to the vertical direction than
in the ride mode. Also, the handlebar 17 extends upward while being inclined in the
normal traveling direction by a larger angle with respect to the horizontal direction
than in the ride mode. The seat 18 extends downward along the stay 15. In the Kickboard
mode, the user U is in a posture in which the user U faces in the normal traveling
direction and holds the handlebar 17 with one of the feet on the ground and the other
on the object mounting portion 13b. This allows the user U to move by human power
while kicking the ground with the foot. For the Kickboard mode, it is preferable that
the electric-powered vehicle 10 have a suitable lock mechanism that is capable of
manually or electrically locking the bearing member 14 against rotation about the
turning axis to fix the axis of the coasting wheel 12 in the direction coinciding
with the vehicle width direction.
[0020] A fourth mode of the modes is a folding mode. Referring to Fig. 5, in the folding
mode, the electric-powered vehicle 10 is folded down such that the frame 13 and the
stay 15 are overlapped with each other. The handlebar 17 extends toward the drive
wheels 11 along the stay 15. The seat 18 extends away from the drive wheels 11 in
the direction in which the stay 15 extends. This allows the user U to carry the electric-powered
vehicle 10 while gripping the grip portion 18a and rolling the drive wheels 11.
[0021] The present embodiment achieves the following advantages.
- (1) In the present embodiment, the user U is allowed to use the electric-powered vehicle
10 as an electrically operated vehicle by taking the posture of being seated on the
seat 18 while holding the handlebar 17 in the ride mode. Also, the user U is allowed
to mount and carry the object B on the object mounting portion 13b, in other words,
use the electric-powered vehicle 10 as a cart, by taking the posture of standing on
the ground without being seated on the seat 18 while holding the handlebar 17 in the
cart mode.
- (2) In the present embodiment, the stay 15 is located on the leading side of the object
mounting portion 13b in the traveling direction in the ride mode (the normal traveling
direction). The traveling direction in the cart mode (the reverse traveling direction)
is set reverse to the traveling direction in the ride mode. That is, the stay 15 is
located on the trailing side of the object mounting portion 13b in the traveling direction
in the cart mode. The user U is thus allowed to hold the handlebar 17 on the further
trailing side of the stay 15 in the traveling direction in the cart mode. This ensures
a comparatively large space for the object mounting portion 13b, which is located
on the leading side of the stay 15 in the traveling direction in the cart mode. Further,
if, in the cart mode, the user U needs to be in a posture holding the handlebar 17
while stretching his(her) arms over the object mounting portion 13b, for example,
the stay 15 or the handlebar 17 needs to be extended or inclined toward the user.
However, in the present embodiment, such extending or inclining of the stay 15 or
the handlebar 17 is unnecessary.
For example, if the stay 15 needs to be inclined toward the user U to an excessive
extent, the stay 15 is likely to interfere with the object B on the object mounting
portion 13b or limitation is set on the height of the object B mounted on the object
mounting portion 13b. However, the present embodiment restrains the above-described
interference or relaxes the limitation on the height.
- (3) In the present embodiment, the stay 15 extends upward from the frame 13 at the
positions corresponding to the drive wheels 11. The weight of the user U seated on
the seat 18 is thus easily applied to the drive wheels 11. This facilitates transmission
of the drive force of the drive wheels 11 to the ground.
- (4) In the present embodiment, of the drive wheels 11 and the coasting wheel 12, the
drive wheels 11 are located on the leading side in the traveling direction in the
ride mode (the normal traveling direction), and the drive wheels 11 have a larger
diameter than the coasting wheel 12, which is located on the trailing side. As a result,
when traveling in the ride mode, the wheels on the leading side in the traveling direction
(the drive wheels 11), each of which has the large diameter, smoothly get over uneven
spots such as bumps and dips on the ground surface such as steps.
- (5) In the present embodiment, the drive wheels 11 are located on the trailing side
of the object mounting portion 13b in the traveling direction in the cart mode. For
a case in which the electric-powered vehicle 10 is moved by human power, the drive
wheels 11 are configured to, in a state in which the electric motors are not energized,
rotate basically at equal speeds to cause the electric-powered vehicle 10 to advance
in a straight line. However, in the cart mode, due to the fact that the coasting wheel
12, which is located on the leading side of the two drive wheels 11 in the traveling
direction, are rotational about the turning axis, the user U is allowed to smoothly
turn the electric-powered vehicle 10.
- (6) In the present embodiment, by changing the angle of at least one of the frame
13, the seat 18, and the handlebar 17 with respect to the stay 15, the shape of the
electric-powered vehicle 10 is modified to utilizes the cart mode, in which the user
U is allowed to easily carry an object B or that a large-sized object B can be mounted
on the electric-powered vehicle 10.
In the cart mode, the object B can be carried by moving the electric-powered vehicle
10 electrically or by human power. Particularly, in a case in which the electric-powered
vehicle 10 is moved by human power, the object B is carried without consuming electric
power.
- (7) In the present embodiment, by changing the angle of at least one of the frame
13, the seat 18, and the handlebar 17 with respect to the stay 15, the electric-powered
vehicle 10 is switched selectively among the four types of modes, which are the ride
mode, the cart mode, the Kickboard mode, and the folding mode. This ensures efficient
movement corresponding to the purpose of use.
[0022] The above-described embodiment may be modified as follows.
[0023] In the above-described embodiment, the electric-powered vehicle 10 may be used by
the user U in the posture standing upright on the foot rest portions 13d, which is
a stand-up posture, in the ride mode.
[0024] In the above-described embodiment, the drive wheels 11 and the coasting wheel 12
may have substantially equal diameters. Alternatively, the coasting wheel 12 may have
a larger diameter than the drive wheels 11.
[0025] In the above-described embodiment, the stay 15 may extend upward from the frame 13
at a position corresponding to the coasting wheel 12.
[0026] In the above-described embodiment, the ride mode and the cart mode may employ the
same traveling direction.
[0027] In the above-described embodiment, two coasting wheels 12, not the single coasting
wheel 12, may be employed. In this case, the coasting wheels 12 may be arranged to
be spaced apart from each other in the vehicle width direction.
[0028] In the above-described embodiment, the seat 18 extends downward along the stay 15
in the cart mode. However, the invention is not restricted to this. The seat 18 may
extend in the reverse traveling direction from the upper ends of the arm portions
16 as in the ride mode.
